# Cosmos 3 AI — full brief

https://cosmos3ai.org is an independent online workbench for NVIDIA Cosmos 3 Super. It is not affiliated with, sponsored by, or endorsed by NVIDIA.

## What the site offers

Two generation modes from the Cosmos 3 Super model family, behind one account and one credit balance:

- Text to image via the Cosmos3-Super-Text2Image variant. Write a prompt, pick an aspect ratio, and get a JPEG image (PNG is selectable in the dashboard).
- Image to video via the Cosmos3-Super-Image2Video variant. Upload one start image plus a prompt and get a 1–7 second MP4 clip. There is no text-only video mode and the output has no audio track.

## Model facts

- Cosmos 3 Super is the largest variant of NVIDIA's Cosmos 3 model family, released on May 31, 2026 on Hugging Face and GitHub.
- The family has three sizes: Super (~64B parameters), Nano (16B), and Edge (4B).
- Image generation parameters: negative prompt supported; inference steps 1–50 (default 28); guidance scale 0–20 (default 4).
- Aspect ratios for both modes: 1:1, 3:4, 9:16, 4:3, 16:9.
- For video, the start image is resized and center-cropped to the chosen ratio and used as the clip's first frame.
- Video output is a silent MP4 file, 1–7 seconds.

## Credits and pricing

- Each Cosmos 3 Super image costs 8 credits.
- Video costs 10 credits per second of output, so a clip costs 10–70 credits.
- New accounts get 10 free credits on first claim.
- Credits for a failed task are refunded automatically.
- Subscriptions give a monthly credit allowance; credit packs are pay-as-you-go and never expire.
